Here is an example (saying you are in C:\ and your source file is in C:\SOURCE):

C:\> cd source
C:\SOURCE>gcc test.c -o test.exe

That will create test.exe from the test.c source file. You need to be in the
directory your program is in to compile it. If you want to use rhide, you need
to go to the directory your source is in and type rhide at the DOS prompt. GCC
is a command line driven compiler.

Compiling and Linking are two seperate stages of the compilation process.
Compiling takes the source files and construct from them "object files". A
project can have several object files. The next stage is called linking. Linking
consists of taking your now-created object files, linking them together (thus
the name), and creating an executable file.

Please read the README.1ST file that comes with your DJGPP distribution. It
contains important information that you need to learn.

This is because are trying to compile a C++ program without linking the C++
libraries.

cd \myprograms\hello

It's a shame that the world of Windows has completely obsoleted the need for the
computer user to learn at least some basic DOS commands. Maybe you should get a
book on how to use DOS (note, DOS, not Windows).
